Ranking the Temperature Scales
To understand how to rank the size of a degree on different temperature scales, we will compare Celsius, Fahrenheit, and Kelvin based on the same physical properties (freezing and boiling points of water).
Freezing and Boiling Points
- Celsius Scale:
- Freezing Point: 0°C
- Boiling Point: 100°C
- Degree Size: 100 degrees between freezing and boiling points.
- Fahrenheit Scale:
- Freezing Point: 32°F
- Boiling Point: 212°F
- Degree Size: 180 degrees between freezing and boiling points.
- Kelvin Scale:
- Freezing Point: 273.15 K
- Boiling Point: 373.15 K
- Degree Size: 100 degrees between freezing and boiling points.
Calculating Degree Size
- Celsius:
- 1°C = 1 degree
- Fahrenheit:
- 1°F = 5/9°C ≈ 0.56°C
- Kelvin:
- 1 K = 1°C (the size of a degree is the same as Celsius)
Ranking the Degree Sizes
Based on the size of a degree:
1. Celsius & Kelvin: Both have the same degree size (1°C or 1 K).
2. Fahrenheit: The degree size is smaller than both Celsius and Kelvin (0.56°C).
Conclusion
In summary, the ranking from greatest to smallest degree size is:
- Celsius & Kelvin (tie)
- Fahrenheit
Understanding these differences is crucial for accurate temperature conversions and scientific applications.
